  • Method and system for disposing of contaminated paraffin wax in an ecologically acceptable manner
    Patent number: 5254177
    Abstract: A method of treating blocks of waste paraffin wax entailing initially subdividing the wax into particles less than one cubic inch in size, and preferably in elongated string or rod form, then intimately mixing the particles with a viscous hydrocarbon liquid in a first mixing zone by agitation. The mixture is passed through a centrifugal pump where further mixing and further comminution of the wax particles occurs as a result of cavitation and pump impeller impact. A slurry of wax in hydrocarbon is discharged from the centrifugal pump and recycled at least once back through the first mixing zone and then back to the pump.
